I can't imagine that anyone actually thought this would work.
In a town that small, it's a safe bet that everyone knows everyone, and most are related at least by six degrees. Invariably, anyone who relocates there is going to viewed suspiciously at best, and treated like the outsiders they truly are. Likely few, if any, of the resident's made any meaningful effort to fit in.
I also suspect that the Tristani's didn't go out of their way to fit in. A Lexus, gold chains, and a Rolex are not the order of the day. Might as well drive around with a boom-boom-thump radio in your car while your at it.
I can understand the motivations of the parties involved. Most of us want to live and raise our families in a place where we feel safe. If one is looking to relocate to a more rural surrounding, it isn't necessary to move to the middle of nowhere in a place as inhospitable as North Dakota. Think about it, there is a reason that small towns like Hazelton are dying, as people are forced to move on for better opportunity's. That's not a criticism of small towns, in North Dakota or elsewhere. It is just a stark reality of our times.
